I've only found one post in existence stating anything about this whatsoever, saying it "overflows" at about this amount. I'm not really sure how or why it "overflows".
But more importantly - are there any ways to fix this? Or do I have to keep my life under ~33k to play?
Its a visual bug when you reach said amount, you don't have to worry about it at all.
However when it happens with mana you do have to lower your mana as a result of it. If you are at 100/33k mana and your spell costs 101, even though you are overflowing your mana, the game thinks you currently have 100 mana only.
Unfortunately it doesn't matter if it's purely a visual bug or not. Once I hit ~32768, my life overflows, constantly making me think it's empty, and freaks me the hell out incessantly as I hit a pot and start evading, thinking I just got hit with massive burst.
This happens every few seconds; I can't really play like that
